Description

Technical Field

[0001] The invention belongs to the field of petrochemical industry, and in particular relates to a supporting structure capable of satisfying natural heat compensation of a large-diameter flare pipeline. Background Art

[0002] The flare pipeline refers to the flammable gas emission pipeline of the whole plant. The flare pipeline should be sloped to the liquid separator and water seal tank with a slope of not less than 0.2%. If there is a low point, a liquid separator needs to be set up. Therefore, under normal circumstances, a liquid separator is set up within 1,000 meters. Because the temperature is high when the flare is vented, natural heat compensation, that is, flat bend π bend, needs to be set up every 200 meters or so. With the expansion of the scale of the device and the increase in the number of devices, the diameter of the flare pipeline of the whole plant becomes larger, and the number of pipelines increases. Large factories have at least 3 flare lines, namely high-pressure flare line, low-pressure flare line, and acid gas flare line. The flat bends of the high-pressure flare line, low-pressure flare line, and acid gas flare line need to meet certain requirements. However, in the reconstruction and expansion of the factory, the space near the pipe rack of the whole plant is often limited, and the requirements of flare heat compensation cannot be met. In addition, in the prior art, high-pressure flare lines, low-pressure flare lines and acid gas flare lines cannot be parallelized and can only be distributed in layers, that is, the pipe rack is set up in multiple layers, one layer is installed with high-pressure flare lines, and the other layer is installed with low-pressure flare lines. This arrangement wastes space and the flare pipelines cannot meet the requirements of thermal compensation. Then how to plan the thermal compensation of the flare line and how to achieve the support becomes a difficult problem, which is also an urgent problem to be solved. Summary of the invention

[0003] In order to overcome the existing deficiencies, the purpose of the present invention is to provide a support structure that enables different large-diameter torches to be arranged in parallel and can meet the requirements of thermal compensation.

[0004] The purpose of the present invention is to achieve the following technical solution. According to the present invention, a support structure that satisfies the natural heat compensation of a large diameter flare pipeline is proposed.

[0005] A plurality of flare pipelines are arranged in parallel on the support structure, and the support structure comprises a first support assembly, a second support assembly and a third support assembly. The first support assembly and the second support assembly are arranged on one side of the factory road, and the third support assembly is arranged on the other side of the factory road. A plurality of trusses are fixedly arranged between the third support assembly and the second support assembly, and the trusses cross the factory road in a direction perpendicular to the factory road. The flare bend of the flare pipeline is arranged on the truss at a position above the factory road. The flare bend of the flare pipeline is located above the factory road, and the space above the factory road can be fully utilized so that the flare bend can realize thermal compensation of the flare pipeline above the factory road, thereby meeting the thermal compensation requirements.

[0006] Furthermore, the multiple support columns within each support component are arranged in rows. Each support component includes multiple support columns, and a first crossbeam and a sixth crossbeam are provided between two adjacent support columns in each support component. The two ends of the first crossbeam are fixedly connected to the tops of two adjacent support columns respectively, and the two ends of the sixth crossbeam are fixedly connected to the middle parts of two adjacent support columns respectively.

[0007] Furthermore, the number of support columns included in the first support component is the same as the number of support columns included in the second support component. The support columns in the first support component and the second support component are in one-to-one correspondence, and the two corresponding support columns form a support column group. A second crossbeam for supporting the parallel flare pipelines is fixedly provided between the two support columns of a support column group.

[0008] Furthermore, a third crossbeam is also fixedly provided between two adjacent support columns of a support column group. Both the second crossbeam and the third crossbeam are arranged in a direction perpendicular to the plant road. The two ends of the second crossbeam are fixedly connected to the tops of the two support columns of a support column group respectively, and the two ends of the third crossbeam are fixedly connected to the middle parts of the two support columns of a support column group respectively.

[0009] Furthermore, the flare pipelines all include a straight part and a flare π bend that are interconnected. The first support component, the second support component, and the second crossbeams provided on the corresponding support columns mainly support the straight part of the flare pipelines; the truss between the third support component and the second support component is used to arrange and support the flare π bend, so that the flare π bend is located above the plant road to make full use of the space above the plant road, thereby meeting the thermal compensation requirements.

[0010] Furthermore, the truss is used to support the flare π bend of the truss flare pipeline. The arm length of the flare π bend is adjusted on the truss above the plant road according to the temperature of the flare pipeline and the size of the flare diameter, so that the flare pipeline meets the flare thermal compensation requirements.

[0011] Furthermore, the third support component includes at least a fifteenth support column, a sixteenth support column, and a seventeenth support column. A first truss is provided between the fifteenth support column and a support column corresponding to the second support component, a second truss is provided between the sixteenth support column and a support column corresponding to the second support component, and a third truss is provided between the seventeenth support column and a support column corresponding to the second support component. The third support component and the second support component are located on different sides of the plant road, so that the first truss, the second truss, and the third truss span across the plant road in a direction perpendicular to the plant road, so that the flare π bend provided above the truss is located above the plant road, and the flare pipeline uses the space above the plant road for thermal compensation.

[0012] Further, a plurality of horizontal supports are provided between the second truss and the third truss; a plurality of first inter-column supports are provided between the two support columns corresponding to the sixteenth support column and the seventeenth support column within the second support assembly, and a plurality of second inter-column supports are provided between the sixteenth support column and the seventeenth support column. The horizontal supports and the inter-column supports act together to counteract the horizontal force generated by the temperature of the torch pipeline.

[0013] Further, each horizontal support and inter-column support includes two angle irons in an "X" shape, and the intersection position in the middle of the two angle irons is connected by welding.

[0014] Further, each truss includes a truss upper chord and a truss lower chord. A fourth cross beam is fixedly provided between the first truss upper chord and the second truss upper chord, and between the first truss lower chord and the second truss lower chord; a fifth cross beam is provided between the second truss upper chord and the third truss upper chord, and between the second truss lower chord and the third truss lower chord.

[0016] 1. The third support assembly and the second support assembly are located on both sides of the factory road, and a plurality of trusses are fixedly provided between them. The torch π bend of the torch pipeline is arranged at a position above the factory road on the truss. The torch π bend of the torch pipeline being above the factory road can make full use of the space above the factory road, so that the torch π bend realizes the thermal compensation of the torch pipeline above the factory road, thus meeting the requirements of thermal compensation.

[0017] 2. The arm length of the torch π bend is adjusted according to the temperature of the torch pipeline and the size of the torch diameter in the space above the factory road, so that the torch pipeline meets the requirements of torch thermal compensation.

[0028] Please refer to Figures 1 to 5, a support structure that meets the natural thermal compensation of large-diameter flare pipelines. Multiple flare pipelines are arranged in parallel on the support structure. In this embodiment, the high-pressure flare pipeline 11 and the low-pressure flare pipeline 12 arranged in parallel are shown. In other embodiments of the present invention, other flare pipelines arranged in parallel can be added, such as acid gas flare lines, etc. The support structure includes a first support component, a second support component, and a third support component. The first support component, the second support component, and the third support component all include multiple support columns, and the multiple support columns in each support component are arranged in rows. Each support column is fixedly installed on the bottom surface. A first cross beam 5 and a sixth cross beam 15 are arranged between two adjacent support columns in each support component. The first cross beam 5 and the sixth cross beam 15 are used to provide support force to adjacent support columns. Two ends of the first cross beam 5 are fixedly connected to the tops of adjacent two support columns respectively, and two ends of the sixth cross beam 15 are fixedly connected to the middle parts of adjacent two support columns respectively. The first support component and the second support component are arranged on one side of the factory road, and the third support component is arranged on the other side of the factory road.

[0029] In this embodiment, the first support assembly includes a first support column 101, a second support column 102, a third support column 103, a fourth support column 104, a fifth support column 105, a sixth support column 106, and a seventh support column 107; the second support assembly includes an eighth support column 201, a ninth support column 202, a tenth support column 203, an eleventh support column 204, a twelfth support column 205, a thirteenth support column 206, and a fourteenth support column 207. The first support column 101 to the seventh support column 107, and the eighth support column 201 to the fourteenth support column 207 are all arranged in rows along the direction parallel to the factory road on the same side of the factory road; the number of support columns included in the first support assembly is the same as the number of support columns included in the second support assembly. In other embodiments of the present invention, the number of support columns included in the first support assembly and the second support assembly is set according to the actual situation. The support columns in the first support assembly and the second support assembly are in one-to-one correspondence, and two corresponding support columns form a support column group, that is, the first support column 101 and the eighth support column 201 form the first support column group, the second support column 102 and the ninth support column 202 form the second support column group, the third support column 103 and the tenth support column 203 form the third support column group, the fourth support column 104 and the eleventh support column 204 form the fourth support column group, the fifth support column 105 and the twelfth support column 205 form the fifth support column group, the sixth support column 106 and the thirteenth support column 206 form the sixth support column group, and the seventh support column 107 and the fourteenth support column 207 form the seventh support column group. A second cross beam 6 and a third cross beam 8 are fixedly arranged between the two support columns of each support column group, and both the second cross beam 6 and the third cross beam 8 are arranged in the direction perpendicular to the factory road. The two ends of the second cross beam 6 are respectively fixedly connected to the tops of the two support columns of a support column group for placing the torch pipeline and jointly acting with the corresponding support column group to support the torch pipeline. The two ends of the third cross beam 8 are respectively fixedly connected to the middle parts of the two support columns of a support column group. Please refer to Figure 1 , the high-pressure torch pipeline 11 and the low-pressure torch pipeline 12 are arranged in parallel on the support structure ( Figure 1 in which is only a part of the torch pipeline), both the high-pressure torch pipeline 11 and the low-pressure torch pipeline 12 include a straight part and a torch π bend that are interconnected. The first support assembly, the second support assembly, and the second cross beam 6 arranged on the corresponding support columns mainly support the straight part of the torch pipeline.

[0030] In this embodiment, the third support assembly includes the fifteenth support column 301, the sixteenth support column 302, and the seventeenth support column 303. In other embodiments of the present invention, the number of support columns included in the third support assembly can be set according to actual usage conditions. The relative distance between the third support assemblies can also be set according to actual usage conditions, that is, the relative distance between the support columns of the third support assembly and the corresponding support columns of the third support assembly is adjusted according to the actual situation to determine the specific installation position of the third support assembly. The fifteenth support column 301, the sixteenth support column 302, and the seventeenth support column 303 are arranged in a row along the direction parallel to the factory road on the side away from the first support assembly and the second support assembly. The fifteenth support column 301 is correspondingly arranged with the third support column group, that is, the fifteenth support column 301 is correspondingly arranged with the tenth support column 203 and the third support column 103, and the three form a column. The sixteenth support column 302 is correspondingly arranged with the fourth support column group. The sixteenth support column 302, the eleventh support column 204, and the fourth support column 104 form a column, and the seventeenth support column 303 is correspondingly arranged with the fifth support column group and the three form a column. A truss is fixedly arranged between the third support assembly and the tenth support column 203, the eleventh support column 204, and the twelfth support column 205. Since the third support assembly and the second support assembly are on different sides of the factory road, the truss is arranged above the factory road and spans across the factory road, so as to make full use of the space above the road. In addition, the distance between the truss and the road surface of the factory road is at least 6 meters, which does not affect the normal use of the factory road. The second cross beam 6 between the third support column 103 and the tenth support column 203, the second cross beam 6 between the fifth support column 105 and the twelfth support column 205, and the truss act together to arrange and support the torch π bend of the torch pipeline, so as to realize the functions of supporting the torch π bend and absorbing thermal expansion. The torch π bend is located on the truss, that is, the torch π bend is located above the factory road under the action of the truss, so that the torch pipeline can make full use of the space above the factory road. The torch π bend performs thermal compensation above the factory road, so as to meet the requirements of thermal compensation of the torch pipeline.The arm length L2 of the flare π bend of the low-pressure flare pipeline 12 and the arm length L1 of the flare π bend of the high-pressure flare pipeline 11 can be appropriately adjusted according to the temperature of the flare pipeline and the size of the flare diameter, that is, the arm length of the flare π bend is adjusted according to the temperature of the flare pipeline and the size of the flare diameter. After the arm length of the flare π bend increases, the heat absorption and expansion capacity of the flare π bend is better, so that the flare pipeline meets the requirements of flare thermal compensation; therefore, when the temperature of the flare pipeline rises, the relative distance between the third support assembly and the second support assembly can be increased by adjusting the position of the third support assembly, that is, the fifteenth support column 301, the sixteenth support column 302 and the seventeenth support column 303 are arranged at a farther distance from the tenth support column 203, the eleventh support column 204 and the twelfth support column 205, and the lengths of the multiple trusses arranged between the third support assembly and the fifteenth support column 301, the sixteenth support column 302 and the seventeenth support column 303 are increased. The three trusses are combined together to adapt to the flare π bend after the increase in arm length, so as to meet the requirements of flare thermal compensation.

[0031] The truss includes a first truss 701, a second truss 702 and a third truss 703. The first truss 701, the second truss 702 and the third truss 703 jointly support the flare π bend of the flare pipeline, so that the flare π bend is located above the factory road. Furthermore, the flare π bend uses the space above the factory road for thermal compensation to meet the thermal compensation requirements of the flare pipeline. The first truss 701, the second truss 702 and the third truss 703 all include upper chords and lower chords. The upper chords and lower chords of each truss are horizontally arranged, and there is a certain distance between the corresponding upper chords and lower chords of each truss.

[0035] There are two first inter-column braces (not shown in the figure) provided between the eleventh support column 204 and the twelfth support column 205, and the first inter-column braces are used to provide support force for the eleventh support column 204 and the twelfth support column 205; please refer to Figure 5 , there are also two second inter-column braces 10 provided between the sixteenth support column 302 and the seventeenth support column 303.
